This exercise points out to the fact that quantum-mechanical reflections are going to be significant in nanoscale devices and proper modeling of these device structures must take into consideration the quantum-mechanical reflections.

This exercise teaches the students that in the case of strong coupling between the neighboring wells in square and Coulomb periodic potential wells electrons start to behave as free electrons and the gaps that open at the Brillouin zone boundaries become smaller and smaller (thus recovering the free particles dispersion relation).

This exercise demonstrates that the interaction between the wells lifts the degeneracy of the quasi-bound states and if in the limit we have infinite periodic potential it leads to formation of energy bands. Notice that when the interaction is less strong the energy levels are more sharp and the width of the bands is smaller.

This exercise demonstrates to the students how the low-frequency CV curves in MOS capacitors change with changing the gate workfunction, the oxide thickness and the dielectric constant. It also demonstrates the doping variation of the high-frequency CV curves.NSFNSF

This tutorial contains introductory material for Quantum Mechanics for Engineers with emphasis on tunneling, open systems and the definitions of transmission and reflection coefficients and their calculation in the case of piece-wise constant potential energy profiles.NSF
